Currently freeze drying can require a 22-24 hours drying cycle, and must be loaded and unloaded by hand. Both these factors can inhibit large-scale producers looking to push out more product. This technology relates to a dryer and a drying process developed to enhance efficiency in the freeze drying process. In particular, though not solely, this technology relates to a dryer for use in freezing, concentrating or drying a liquid substance which has some solid material in suspension or a substance dissolved in another liquid. This new technique dramatically reduces processing times and can be used as a continuous process thereby increasing throughput and efficiency.
AgResearch is looking for companies looking for new technologies for spray freeze drying of bulk liquid materials.
